Sleeping regression

Hello to everyone.. my son is 8month old now and he keep waking up at night and start crying I don't know if its the Air Conditioner is making my baby cold or something else! He is perfectly fine but am just wondering why So much waking up at night I can barely sleep... and I am a first time mom living in foreign country with my fiancée I can barely speak to my mom due to crises in my home town!!! And going to see a pediatrician is not that easy where money is not involved and we both are looking for a job my fiancée and I.. So its kinda hard to even think that maybe there is something bothering my baby and I can't do anything 😥
